RSDLLibfind()
The function provides a handle for access to the device with the name udName.
VB format:
C format:
C format (UNIX):
Parameters:
Example:
The function must be called prior to all other functions of the interface.
As return value, the function provides a handle that must be indicated in all functions
for access to the device. If the device with the name udName is not found, the han-
dle has a negative value.
RSDLLibwrt
This function sends data to the device with the handle ud.
VB format:
C format:
C format (UNIX):
Parameters:
Example:
This function allows setting and query commands to be sent to the measuring instru-
ments. Whether the data is interpreted as a complete command can be set using the
function RSDLLibeot().
RSDLLilwrt
This function sends Cnt bytes to a device with the handle ud.
